Question

what number can you multiply each length in the scale drawing by to find the actual length?
3
what are the actual length and width of the trampoline?
actual length = ft
actual width = ft

Explanation:

Step1: Analyze the scale

The scale is \(1\) in. : \(3\) ft. This means for every \(1\) inch in the drawing, the actual length is \(3\) feet. So the number to multiply by is \(3\) (from the scale factor).

Step2: Calculate actual length

Given the length \(l = 4\) in. in the scale - drawing. Using the formula \(Actual\ length=Scale - drawing\ length\times Scale\ factor\).

$$Actual\ length = 4\times3=12$$

Step3: Calculate actual width

Given the width \(w = 2\) in. in the scale - drawing. Using the formula \(Actual\ width=Scale - drawing\ width\times Scale\ factor\).

$$Actual\ width = 2\times3 = 6$$

Answer:

Actual length \(= 12\) ft, Actual width \(= 6\) ft
